Vikings quarterback Christian Ponder was optimistic that he'd be ready to play against the Seahawks on Sunday following a shoulder injury he suffered in Thursday's win over the Redskins.

Ponder said his left (non-throwing) shoulder's range of motion on Friday was "terrible". He also felt discomfort in his shoulder over the weekend as he went through rehab treatment but saw progress on Monday.

"Today it's actually pretty good," Ponder said. "It's about trying to get the strength back, trying to get the full functionality back. Range of motion isn't completely there, but it's pretty good."

The Vikings had a short walkthrough on Monday, but Ponder said he'll try to practice on Wednesday and plans to push himself daily. He injured the shoulder late in the third quarter on a goal line collision near the pylon with Redskins defensive back DeAngelo Hall.

"It's not like hindering my throwing motion or anything," Ponder said of the injury. "It's just being able to take a hit or something. We don't have fear that it's going to get worse. It's just going to be able to handle the pain and if I can do it than I'll play."

Vikings head coach Leslie Frazier said the strength of Ponder's shoulder will be the most important factor on whether he plays in Seattle. Frazier reiterated he'd like to see Ponder practice on Thursday if he's going to start.

"You don't want to put him in harm's way," Frazier said. "If he can't protect himself you wouldn't want to put him out there. So we'll have a better when we come back on Wednesday and start practicing. He's made progress, which is encouraging."
